Question

Select the wrong statement regarding membrane channels

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Membrane channels and their properties
	**Related Topics**: Protein structure, ion transport, cell membrane function, selectivity of channels
	**Prerequisites**: Basic understanding of cell membrane structure and function, protein structure, and ion transport.
## SOLUTION PATHWAY
**Given Information**:
	* Statements regarding membrane channel properties.
	* Task is to identify the incorrect statement.
**Method & Steps**:
	1. Analyze each statement individually based on known properties of membrane channels.
		Reasoning: Membrane channels are integral membrane proteins.
		Formula/Rule: N/A
	2. Evaluate statement B: Membrane channels are often gated.
		Working: Gated channels open or close in response to stimuli.
		Key Point: This is a key mechanism for controlled ion transport.
	3. Evaluate statement C: All ions do not pass through same type of channel.
		Working: Channels exhibit selectivity, allowing only specific ions to pass through based on size and charge.
		Key Point: This selectivity is crucial for maintaining membrane potential.
	4. Evaluate statement D: Some channels can form large pores in outer membranes of plastids, mitochondria and some bacteria.
		Result: Statement C is incorrect.
		Verification: Known properties of membrane channels confirm C is the incorrect statement.
## OPTION ANALYSIS
[A] :x: Membrane channels are indeed proteins.
[B] :x: Membrane channels are usually gated.
[C] ✓: This statement is incorrect. Different channels are specific for different ions.
[D] :x: Some channels form large pores in outer membrane of some organelles.
## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Assuming all channels are the same. [How to avoid]: Remember that channel selectivity is a key principle.
		2.[Error 2]: Confusing channels with simple pores. [How to avoid]: Understand that channels are proteins with specific structures.
	**Quick Tips**:
		1.[Helpful shortcut]: Think of channels as highly specialized doorways, not just open holes.
		2.[Memory aid]: Remember 'selectivity' when thinking about membrane channels.

B VENKAT · Answer

They are proteins

B VENKAT · Answer

They are usually gated, i.e., may be open or closed

B VENKAT · Answer

The correct Option is "	All ions pass through the same type of channel"

B VENKAT · Answer

They form a huge pore in the outer membrane of plastids, mitochondria and some bacteria
